孩子马上要上学了，出差路上顺手写个练习口算的程序跟大家分享下，如果家里有同款的宝宝，正好可以拿去，不谢！
先说下自己的需求：
1.基本的计算功能，本来想只写下加法就可以了，想了想顺手就把加减乘除都写了
2.计算的范围可以通过界面修改，这样大概1-6年级都可以用了吧
3.题目的数量可以设定
4.正确错误可以进行统计和反馈
5.如果不希望孩子用电脑，可以生成文件打印到纸上
说完需求，聊下自己的思路
1.设计UI
在这里插入图片描述

2.基本功能

功能比较简单，所以就不每个点都陈述了，主要分享下几个点吧
第一，整数验证，为了避免输入的内容不是整数，我对6个lineEdit单行输入框进行了整数输入限定。方法是通过PyQt5里面的QreExp模块设定，利用正则re判断，代码如下：

整数校验器

regExp = QRegExp('\d*')
int_num = QRegExpValidator(regExp)
self.lineEdit.setValidator(int_num)

第二，加减乘除按钮的互斥设定。两个思路，一个是通过sender()方法，点击按钮的同时发射当前按钮的内容来判断。第二个方法，当单击某个按钮时，其他三个按钮的状态相反，需要4个同类型的函数。因为考虑到后面计算过程的判断，自己选择了第二个方法，虽然多了几行代码，但是相对好理解。

def signal01(self):self.pushButton.setChecked(True)self.pushButton_2.setChecked(False)self.pushButton_3.setChecked(False)self.pushButton_4.setChecked(False)self.label_3.setText('+')
def signal02(self):self.pushButton.setChecked(False)self.pushButton_2.setChecked(True)self.pushButton_3.setChecked(False)self.pushButton_4.setChecked(False)self.label_3.setText('-')
def signal03(self):self.pushButton.setChecked(False)self.pushButton_2.setChecked(False)self.pushButton_3.setChecked(True)self.pushButton_4.setChecked(False)self.label_3.setText('×')
def signal04(self):self.pushButton.setChecked(False)self.pushButton_2.setChecked(False)self.pushButton_3.setChecked(False)self.pushButton_4.setChecked(True)self.label_3.setText('÷')

第三，计算过程，加法和乘法相对比较简单，就不赘述了。因为小学没有负数，所以减法需要先判断大小，将较大的数设置在前面。除法因为牵扯到小数，孩子还做不了，所以进行了整除的设定，通过while循环先找到可以整除的两个数，再进行计算。

while 1:random_num01 = random.randint(int(self.lineEdit_2.text()),int(self.lineEdit_3.text()))  # 第一个要计算的数random_num02 = random.randint(int(self.lineEdit_4.text()),int(self.lineEdit_5.text()))  # 第二个要计算的数if random_num02 == 0:continueif random_num01 < random_num02:a = random_num02b = random_num01if a % b == 0:self.label_2.setText(str(a))self.label_4.setText(str(b))self.lineEdit_result.setText('')

第四，保存。这应该是最简单的功能，直接for循环保存到文件夹即可。

def save(self):if self.lineEdit.text()!='' and self.lineEdit_2.text()!='' and self.lineEdit_3.text()!='' and self.lineEdit_4.text()!='' and self.lineEdit_5.text()!='':num =int(self.lineEdit.text())range01 =int(self.lineEdit_2.text())range02 =int(self.lineEdit_3.text())range03 =int(self.lineEdit_4.text())range04 =int(self.lineEdit_5.text())signal = self.label_3.text()file_name =time.strftime('%Y_%m_%d_%H_%M_%S',time.localtime())+'.txt'with open(file_name,'w+',encoding='utf-8') as f:for i in range(num):result=str(random.randint(range01,range02))+' '+signal+' '+str(random.randint(range03,range04))+'='+'\n'f.write(result)QMessageBox.information(self,'状态提示','文件已保存，请在软件相同文件夹下打开\n文件名：%s'%file_name)

另外，几个细节分享。
1.除了整数验证之外，对是否输入（不为空）进行了判断。
2.因为UI调整了很多次，为了每次修改不会影响后续的代码，采用了调用的方式，具体可以参考我的上一篇文章【Python心得】解决PyQt5 UI更新同步问题

最好的学习方法是输出，附上全部代码，需要的随意吧。一共2个部分，主代码和UI部分。
